A mid-week storm could dump anywhere from two to eight inches of snow on Fairfax County, according to the National Weather Service.

A strong, low-pressure system will enter the region this afternoon, with rain likely changing to snow overnight, according to National Weather Service meteorologist Jason Elliott. The storm, which is expected to hang around until early Wednesday afternoon, will bring temperatures in the lower and mid 30s and north-eastern winds with gusts of up to 30 miles per hour.

“There’s still a decent amount of uncertainty this close to the event,” said Elliott at 10:15 a.m. Tuesday. “The critical question is where the temperatures end up. We know there’s going to be a lot of precipitation. The temperature will determine whether most of it comes in the form of rain or snow.”

In Fairfax, precipitation will most likely begin as rain around 3 p.m. Tuesday before changing to snow around midnight. Several counties west of Fairfax, including Loudoun, could get up to a foot of snow.

Elliott added that strong winds, combined with heavy, wet snow on tree limbs and power lines, could lead to power outages across the region.

In anticipation of the storm, the Fairfax County Police Department is urging motorists to be prepared and make sure their vehicles are equipped with a well-stocked winter driving kit.

The office is also asking residents to stay off the roads during the storm unless travel is necessary.
